To all whoinfit may concern:

, Beit known that I, SnicMUND BACHMANN, a citizen of the United States, residing at Chicago, in the county of Cook andv State Yof illinois, have invented a new anduseful Improvement in Boxes, `of which the following is a' specification. i My invention relates, more particularly, to improvements in boxes formed fromsheets of paper-box board, or other suitable material, involving in .their manufacture the making of a blank of a desired. form and bend- 4ing such blank along folding lines to pro- '15..- f vreinforcing of the corners of boxes of the duce the box. My primary' objects are to provide for the variety above referred to and to form such rein-forcement from the corners of 'the blank. Another important object is to form the reinforcements as above stated and to vprovidelocking means preferably automatic in. operation and in the form of lips, or tongues, for maintaining the reinforcements for the box-corners in position.

Referring to the accompanying drawings in which I vhave illustrated my invention as embodied in a plurality of forms of constructioIr-Figure 1`is a perspective view of Vso .a foldable *paper-board' box illustrating aconstruction thereof embodyingthe preferiedform of my invention. Fig. 2 `is a view of the same showing the box in collapsed 'condition Fig. 3 is a vplan view of fthebiank fromfehich'the box illustrated in the preceding figures is formed.v Fig. 4 is a broken perspective view, diagrammatic .in itsnature, showing a corner-portion of the boxblank in the condition of its re resentation in Fig. 3, but 'with a portion o its cornerextension folded back upon itself and against an` adjacent Wall-portion ofthe blank. Fig. portion of the blank upon 'which the corner` extension is folded in erect position at a right-angle to the basef of the blank. Fi 6 is a View of the same showing both wal s erected with the corner-extension folded into position for forming a reinforced corner of similar corner-portions off' the boxand righting its walls. Fig. 7' isv a brokenplan view representing one of thefour similarly constructed vcorners of the blank for another form ofembodiment ofmy invention. I

Fig. 10 is a view similar to Fig. 9 showing both Walls erected andthe corner-extension folded to form a reinforced corner for thebox. Fig. 11 is a Similar view showing the box collapsed. Fig. 12 is a view like Fig. @representing a blank for another form of embodiment of my i`n' vention. Fig. 13 is a similar view of the sameshowing the "corner-extension bent upo itself and against the wall-portion carry-inr` it. Fig'. 14 is a similar view showing the wall-portion against whichthe extension lies, folded at its'connection with the base to lie against the latter. Fig. 15 is a similar viewV showing both of the Walls righted and the corner-extension folded to form a reinforced corner for the box. Fig. l16 .is a similar View showing the box collapsed. Fig. 17 is a. plan view of one of four similar corner-portions of a blank for forml ing still anotherlform of box embodying my invention. Fig. '18 is a perspective view of the same-showing a portion of the cornerextension'folded upon itself 'and against the adjacent wall-portion of' the blank. Fig. 19 is ay similar view showing the wall-portion upon which the corner-extension is folded as represented ,in Fig. 17 in erect position at a right-angle to the base-portion of the blank. Fig. 20 is a similar view sented in erect dperative position and the corner-extension olded to Iform a reinforced corner for the box. Fig. 21 is a similar view showing thebox-collapsed. Fi 22 is a plan view like Fig. 7 showing a orm of blank from whicli`a box of another form of embodiment'ef. my invention may .be produced. Fig. 23 is a broken perspective view of the blank-shown in Fig. 22 with its corner-extension folded upon itself and against the'wall-port-ion of the box carrying it.

. mg four walls hingedly connected with the-` box, warrig. 26,11 similar view vof the box in collapsed condition. v

Each 4of the five construct-ions' of box selected .for illustrating a different embodiment of my invention is ofthe collapsible type involving, generally stated, a base havbase,` with extensions carried-on the ends of opposed walls adapted to befolded atwise against thejadjacent walls of the box and held in position against accidental displacement by flaps carried by the' walls against which the extensions are folded.,

Referrin particularly to Figs. 1. to6, inclusive, t e box in its nonoollapsed condition is represented at 27. The blank 28 fromlwhich this box is formed consists of l` an oblon rectangular sheet of boxfboard,

or the li e materlal, adapted to be folded along the parallel dotted lines 29 and 30 to form the box-sides 31 and 32 hingedly connected with a base 33, andalong the dotted lines .34 and 35 to form the ox-ends or end-walls 36-and V37, the dot-ted lines being,

` connecting the adjacent endsof the lines 46v folding line 55 thus-.alfording a lipor tongue L 56 on eachextension. 'By cutting the-exten- `ties Aof the foldin .and along diagona lines 39, (also preferably by preference, creases 'to facilitate folding theparts. Each line 31 and 32 integisects the lines 34 and 35 to form the four rectangular corner-sections, 'or extensions of= the side-walls, 38 of the blank, adapted to be folded inwardly-along t outer extremilines 2 30, 34 and 35,

creases) to form the triangular sections l40 and 41. On each end of the blank is a flap 42 reaching preferably from the plane of the foldinig line 29 to that of the folding line30, each ap beging adapted to be folded at a dotted line 43, as hereinafter described. The

corner-extensions' 38 are\of oblong, rectangular shape, the diagonal folding'1ine39 Vof each extension preferably extending from the intersection o the lines 34 and V29, for for lng the sidesof the box at equal angles thereto, to a line of severance 44 parallelmg the outer edges of the sides of the blank and terminating at a folding line '45 extend,l

ing parallel with the edges'of the ends of the blank. Each corner-extensin is cut valong lines 46 and 47 paralleling each ther and the". ends of the gblank, and along the parallel lines 48, 49l and 50 the lines 48 and" 49 extendinr from the line 46 intermediate its ends to the dotted line`39, and the line 50 and '47.- y The main sections'thus,- partially severed from the extensions 38, are indicated at 51 and each of 'these sections has a fold-- in line 52 parallel with its free edge 53 aigording a reinforcing flap 54-and a diagonal foldinggline 55 extending from theintersectionof the lines 46 and 50 to the inner edge fof the extension, the provision ofthe sions 38 along the lines 44", 48 and 49, tongues 57 and 57a* are afforded, either or both" ofl v' which are bendable along the linesvr To form the box 27 from the blank 33, the

sections 51 of the extensions are folded upon f the lines 45 to the position of the one shown in Fig. 4. The walls 31 and 32 with the sections-51'thus lying vagainstthem are then turned upon the folding lines 29 and 30V 'l to upright position, as illustrated in Fig. 5,

whereupon the end-'walls 36 and 37 of the box are righted, and the extensions 38 folded upon ,the lines'39, 55, 34, 35,29, v30 and Y52 flaps 42 may then be folded inwardly alongV the folding lines-43 to overlap the extensions 38 for holding the 'latter in place, in which position these flaps inthe construction illustrated are designed to be held in place by turning the tongues 57a upward from their positionrepresented in Fig. 6 along the dot-A A ted folding line 39 to extend'at their free ends through slots 58 located in the endportions ofV these flaps. The tongues 57 areV designed to be secured to the end walls in vthe position illustrated in Figs. 1 and 6 in any suitable manner, as by pasting, the provision of the tongues 57 being of especlal advantage in constructions having low Walls, Y

as they .serve to resist any tendency of spreadlng of the walls while the box is in use. The box thus formed may be collapsed tothe condition represented in Fig. 2 by Y p first withdrawing the tongues 57'l from the slots 58 and then pressing the end-Walls 36 and `37 outward and side-walls 31 and 32 inward, to 'cause them to assume the posi# tions illust-ratedin Fig. 2. The box may be-righted from its collapsed condition, by

turning the endI and side walls-at hinged connection with the base to upright position, thereby causing the extensions 38 to fold along the lines 39to theposition i strated in Fig. 6, and then fastening the flaps 42 in position against the extensions 38 by means of the tongues 57 a as described.

It will be understood that instead of forming the box froin the blank b the successive operations illustrated in ig's. '4, 5 .and 6, the blank, afterthe portions 51 of the extensions have been folded to the'position represented of thefone in Fi1g.v4, may` be yfolded -into .the condition illustrated in .i

. 2 by merelyv folding theside wallsinwar y toward the 'base to cause them and the sections' 49 to lie adainst lthe base and vthe tongues 57 and ft'folded along the lines 39, to lie against the' end-wallsldf the box. The bex, thus provided in 'collapsed condition, niay be righted as hereinbefore de-` scribed of the blank in its condition shown .y foldingv between' the sections 40 and the :inner surfaces ofthe end-portions ofthe I walls 36 and 37' of the box, affording lock.

. ing means for holding the sections -51 in position at the boxcorn`ers, these locking means operating by the mereact of righting the blank to be locked automaticall'yin place, it` being understood .that the lips 56 are maintained between'the sections 40 and the inner surfaces .of the end-walls of thebox,

:both when the box is righted and when it is collapsed to the form shown in Fig.- 2. In

view of the-fact that the lips 56 lie at .all

timesagainst the face of the portions 41 of the extensions, 38 they I'haybe permanently secured thereto inany suitable way atdesirable points as, for instance, those indicated at 59,.- The ,provision of locking-means.

'54 in position for reinforcing t operating as described fpr holdin e corners renders unnecessary in many forms of box, the use of separable fastening means, such as eyelets, tape', staples, or any other form of separable fastener, onadhesives.

' inclusive, the construction ofv box therein Referringparticularly to Figs. 7 to 11,

' f' illustrated differs from that-presented by the v.preceding figures only in the'formation of its corner-portions. The corner-sections, or

extensions, 60 are formed by the'intersecting of the linesl 29 and 340'with the lines 34 and -angle to the base as 35, each extension being severed along the full'lines 61, 62 and 63, and foldable along lthe dotted lines 64, 65, 66 and 67 and those portions of the lines 29,30, 34 and 35 which4 'extend beyond their intersection with each' other, the provision of the severing lines referred to and the ldott-ed lines 66 the provision of the folding line 67 dening -sections 69 and 70, the

location of thelines 61 to 66 inclusive affording' lips 7 Lend 72 on the sections 6 3. \Each section 68 carries 4atD its outer end a flap 73 foldable along aA line 74.A Av box may be formed from a blank ,thus provided'by rst folding the sections 68 on the dottedlines 66 to cause them to lie flatwise against the sections 69 and'70 andfthe endl-portions ofV the adjacent walls-,3l and 32 as represented of the one in Fig. 8. Thesidewalls31 and `32.1nay then beturned at the foldinglines 29 and 3() to cause them to extend at a right- The'next operation is that of'bendingup the iaps v defining f sections 68 which are free to be folded upon -the lines 66, and

represented in Fig.A 9.'

the end-walls along the `folding lines 34 and 35 to upright posltion relative to the base 33, Vand simultaneously therewith bending the extensions 60 along 'the folding lines 64, 65, 66, G7, 74, andthe outer extremities of the.lines 29, 30, 34'and" 35 to cause the extension to -lie fiatwise against the inner sur' faces of the end-Walls, the lips 71 and 72`to lie bet-Ween the sections 69 and the inner surfaces of these walls, and the flaps 73 to lie Hat-,wise against the' adjacent end-portions of the-walls 31 and 32,.as"represented in`\Fig. 10. The flaps 42 mayl then be bent down to overlap the extensions 60 so positioned, and to be fastened in such .positlon in any desirable manner. The box may be collapsed by pressing the end-walls outward and bending the side-walls inwardly to cause the box to assume, at eachof-its cornerportions,.,the lcondition of the onerepresented in Fig. 11. The bo'x may be righted from its collapsed -condit-ion to upright condition byswin ing the'end and side walls of the box to upright position, thus causing the xtensionsto fold along th lines 64, 65, 66, Z7, 67, 74 and the outer {ex remities of the lines 29, 30, 34 and 35 to 'the position represented in 'Fig 10. It will be noted that the extensions 60 lying atthe corner-portions of the box serve toreinforce the latter, and that the liaps 73 -are held in operative position by the continement of the tongues 71 -and 72 between the extensions 60 and the end-walls of the box.

It is manifest that instead 'of righting the blank by successive operations illustrated in Figs. v8-to 10 inclusive,l it may be folded to the position` illustrated in Fig. 11- by first turning the sections 68 to the position of the one illustrated in FigeS and thereupon folding-the side-Walls 31 and 32 on .the lines 29 'and 30jto cau-se them to lie again'st'the base 33, as illustrated inlfig. 11. `Rightingof the the end-walls inwardly and the side walls outwardly and causingthe extensions to fold along the lines 64, 65, 66, 67 and those'portions of the lines 29, 30, 34 and'35 .which ex tend beyond their intersection with each other. In this construction, as in the construction `represented in the preceding ligures, a reinforcing flap' is provided for ,the corner-portions of the box, and automatically operating means inthe form of tongues are provided for holding these reinforcing means in operative position.A j

Referring particularly to Figs. 12 to 16 inclusive, another form of embodiment of my invention, which diiers from the construction of the last-preceding figures onlyju the construction of its corneis.- rl-he extensions l75 thebox therein .shown represents fcollapsed box may be effected by swinging formed bythe intersecting ofy the lines 29 and 30 with the lines 34 and 35,;'a`re entirelyv severed from the'end-walls-36 and 37 alon the fulllines' 76, 77 and78 and areadapte i' Yto be folded along the dotted lines 79,80, 81

the dotted lines 82,

y Wise against the end-walls 36 and 37, as repprovide means, such as the eyelets Indicated sions to assume the position illustrated of hold-such sections in position for reinforcing' stance the eyelets represented at- 86. 'Ehe adjacent end-walls. After folding the blank represented in the preceding gures only -in resented in Fig. 14. It is preferred that the tabs 85 lying iatwise againstthe end-walls as illustrated be. secured in such'position by any suitable fasteningmedium, as for inend and side walls may then be righted, thus causing the extensions to fold upon the lines 79, 81 and 82 to the position represented in Fig. 15, in which the extensions lie flat'wiseagainst the end-walls andthe tabs are'conined between the extensions 75 and the ends-walls'of the box, thereby hold-' ingl the reinforcing flaps 84 securely in position at the corners of the box. I refer to at 86, for fastening the tabs 85'to the end-- walls, though it will beunderstood that such' means are not necessary ias the tabs by righting the blank will be held between the extensions on which they are carriedand the to the position illustrated in Fig. 1-5 the flaps 42 may be turned down alon the'folding lines 43 to lcausethem to ove ap the exten sions, in which position they may be secured by any suitable means. The box is collapsed by 'pressing the end-walls' outwardly and turning the side-wallsdown. upon the' base, the position the parts assume being that represented of one corner of the box 1n Fig. 16. The box may be righted t operative position by swinging the end and 'sldeywalls upward to a. position at which they extend at right angles to the base, the extensions 7 5. in this operation folding alongthe lines 79,81 and 82, to cause the extenthe one in Fig. 15. It will be notedthat the sections 83, when the box is righted, are so disposed at. thecorners of the box as to reinforce 'theln and that the tabs 85 Aserve to the corners of the box.

Referring. to Figs. 17 t-o-21 inclusive, the construction therein shown differs from that the construction of its corners. In this construction thecorner extensions 87 are formed bythe intersectingA of the lines 29 land 30 with the lines 34' and 35, these extensions being cut alongthe full lines 88 and 89 -and foldable along the linesv90, 91, 92,93

and 94, thereby forming sections carryin reinforcing flaps 96. The box is forme from the blank last described by first folding the sections 95 on the lines 91 tocause them to lie against the adjacent portions of the extensions 87 and the walls 31 and 32, as

illustrated of the one in' Fig. 18, 'and-there .uponfolding the walls 31 and 32 along the` lines 29 and 30 to .cause them to extend at right angles to the base 33 as represented in Fig; 19. vThe end-walls` 36 and 37 may then be righted and simultaneously vtherewith the extensions 87 inwardly folded upon the lines 90, 92, 93 and 94 to cause them to lie against .the end-walls 36and 37 as represented in Fig. 20, whereupon the flaps 42 may be folded alongthe lines 43 to cause them to. overlap the extensions 87 so folded, in which position the flaps may be secured inany suit- V able manner. The constructipn of thebox ,now being described doe's not-lnvolve the use of automatic means for maintaining the reinforcing lia sin position for reinforcing the corners '.o the box, and to insure the to secure them tothe adjacentend-portions of the wallsl 31 and 32 inany suitable way,

as by the eyelets indicated, or by any other suitable fastening medium, at the .points indicated at 97 or 98., or both. The box thus 4righted from. 'the blank shown in Fig. 17, ,may be collapsed as described of the box illustrated in Figs. 12 to 16 inclusive, the po-` sition occupied by the parts of the box when collapsed 'being that lrepresented Iin Fig; 21 of those parts form-ing the corner-portion therein illustrated. It is manifest that this blank instead of being folded in accordance with the successive operations represented in Figs. 18 to 20 inclusive may'be folded to the' form illustrated in Fig. 21, preliminary tothe righting of. the box.

vIn the embodiment ofmy invention illusl trated in Figs. 22 to 26 inclusive, the cornerext'ensions-99 are formed'by the intersecting of the lines 2 9 Aand 30 with the lines 34 and '35, these extensionsfbeing severed from the end-walls 36 and 37 alon the full lines 100 and foldable alongpara lellines 101, A102 and 103, these dotted -lines delining sections 104, each of which carries a reinforcingflap 105.v The blank described may be folded to f form a box by first folding the sections 104 upon the lines 102 to cause them to assume the position of the one re resented in Fig. 23. The side-walls 31 an '32 may then be turned upward along'the folding lines 29 r and 30 ,to causethem to extend at right angles to the base 33, whereu on the lend-walls 36 and 37 may be -righte and simultaneously' therewith the extensions -99 folded upon the lines 101 and-103 to cause the ex-f tensions to extend inwardly-and lie against the end-walls and `side-walls as represented 90.- proper' positioning of the flaps .96, I prefer in F i0'. 25. The flaps .42 may then be folded along the lines 43 to cause them to lie flatwlse against the extensions 99, in which osition they may be secured in any'suita )le mannen` The box may be collapsed by pressing the end-walls outward and foldin-O' the side-walls down upon the base and the j extensipns against the end-Walls as. illustrated 1n F1g..26. Toright this box from its' collapsed condition, the side-walls are first raised to erect position, the extensions then folde'dfinwardly along the .lines 101 and 103 to the position represented Fig. Q5, and the end-walls then righted.

All of the forms 'of boxes represented by the drawings are of the type of collapsible box involving the use of'flaps carried by op- I posed walls adapted to overlap the cornerA-` extensions when the ,box is righted,`which are readily transformable from collapsed to operative condition, and vice versa.

As clearly set vforth in the foregoing de- -l scription, the wall portions of the blanks forming boxes of each of the constructions illustrated may be folded from fiat condition to upright condition,and the flaps 42 then folded over the extensions and fastened in place; or the blanks may be folded to form boxes in collapsed condition as represented of the various forms, from which collapsed condition the boxesare re dily transformable to operative conditio set forth. y

'While I prefer to embody my invention in the types of boxes which are readily operativev to reduce them to collapsed condition for 'shipment or storing, and readily restorable to operative condition for use, I do not as hereinbefore wishto beyunderstood as intending to limit my invention to its embodiment in boxes of these or similar types, as it may be embodied Y in any form of box employing corner-extensions located at the ends of adjacent walls of the box and adapted to lie against walls thereof. Furthermore, while boxes employ- A ing retaining Haps on opposite walls secured thereto in any 'suitable manner are of the type to which I prefer to apply my invention, it is readily apparent that such invention will have .utillty in constructionscorresponding to all of those illustrated with the flaps` 42 omitted. Such omission, however, would require the application to the extensions, after they and the walls had been righted and the box laced in non-collapsed condition, of means not shown) for fastening the extensions to the walls against which they would li'e, and these means might be of any suitable form. f

l The various forms of blanks illustrated in the 'drawings are designed for forming boxes of the'type having their walls extending at right-angles to the base ofthe box.

' The corner-extensions of each of the blanks shown are lthus shown of rectangular shape.

In making boxes of the' type in 'which fthe u walls incline with relation to the base, thus` producing a flaring mouth-box, as is common with berry-boxes `and receptacles for other material, to which class of boxes or receptacles my invention is applicable, the corner-extensions would vary 1n contour as compared with those of the blanks illustrated and would not be strictly rectangular in shape.

It will be noted that the. principal'feature of my invention consists of lthe provision of reinforcing means for the corners of av boxformed from portions `of the corner-extensions, ,and that 'another desirable feature consists in the provision of means which may operate automatically to insure V the maintenance of the reinforcing.` portions of the extensions in position for reinforcing the corners of the box. y

While I have illustrated a forms in which my invention. may be embodied, I do not wish to beunderstood as limiting my invention to its embodiment in these particular forms, as various modifications of the constructions shown and described may be made without departing from the spirit of my invention. Furthermore, my mvention is not limited to boxes lin which the Vcorner-extensions fold against vthe "inner surfaces of walls of the box, it

bein applicable to boxes of thetype Iin whic such extensions overlap the outer surfaces of the walls.

What I claim as new, and desire to secure by Lettersv Patent, is:
